erisera / circuit · v0.0.1 — pre-release

Circuit — the erisera OSS design system

One system, six tools. Circuit is a single set of tokens — neutrals, type, spacing, components — with exactly one dimension that changes per project: an accent hue. This page imports src/index.css and src/palette.js directly — every component below is the real, shipped thing.

Three rules hold the system together: neutrals are hue-stable so scaffolding never clashes with whichever accent is active; semantic color is fixed (success/warning/error/info never rotate); syntax highlighting is fixed. Only --accent moves. See README.md for the full writeup.
